    摘要: A method and an arrangement for trying out in advance prerequisites for introducing new services in a telecommunications system. A base system is described by a specification language, a new service is described by the specification language as separate supplement to the base system description. The base system description and supplement are linked together to form a description of the total resultant system. The total system is then analysed, for example by a reachability analysis. The invention also relates to an arrangement for carrying out the method. The invention solves the technical problem of identifying problems of an interservice interference type with respect to specific services at an earlier stage.

    摘要: A servomotor control system is set forth that assists in overcoming the problem of servomotor shut down during a failure of the programmable control system and/or servo-amplifier. The presently disclosed servomotor control system includes a programmable control system having one or more output signals connected to control a servo-amplifier. The system further includes a servomotor that is connected for control by the servo-amplifier. A safety switch is connected for detection by the programmable control system, the programmable control system controlling the servo-amplifier to brake the servomotor upon detection of the actuation of the safety switch. A delayed braking apparatus is disposed between the servo-amplifier and the servomotor. The delayed braking mechanism is also connected to detect the actuation of the safety switch, and acts to brake the servomotor after a predetermined time period from the detection of such actuation has lapsed.
